I don't think the evidence is strong enough to do this, yet. Not quite.
In the course of investigating #37910, I discovered a flaw whose effect
would be consistent with what we're seeing in #37910 and the current
bug. I intend to commit a fix to this flaw, soon. However, there's
more to #37910 than just that flaw, so #37910 is where I'm spending my
time at the moment.
